Papageorge - B3NA r7V Re your recent note about input to Cheatrec for their PCB data sheet, at thia point I don't know of any changea we ahould recommend to the current sheet. Within the past 10-12 months, as a member of the CMA PCB Panel and chairman of the Health and Toxicity Subcoonlttee on PCB, I have reviewed and suggested changes in the Chemtrec document and It looks like they have responded. The Chemtrec PCB document information now parallels the Monsanto generic PCB Material Safety Data Sheet (copy attached). Confusion does occur among many disciplines. Including the media and public, as to what happens to various comnercial PCB containing products in misuse situations. A good example is electrical fires and possible formation of toxic contaminants from various equipment ingredients which may Include * PCBs, and other adjacent materials that may be combustible including wiring, paint, building materials, etc. Monsanto has taken the position that we will and do provide data regarding PCBs we manufactured. Other products such as transformer and capacitor fluids, etc., were formulated, manufactured, sold, patented, etc., generally by electrical equipment manufacturers. Certainly the responsibility for use of such fluids and providing information about its( use and safety lies there. Among the misconceptions about PCBs is the allegation that PCB fires result in dioxins. This is Incorrect. EPA data demonstrates that in electrical fires pure PCBs don't form dioxins. Other components of the dielectric fluid, l.e., trichlorobenrenes, cause dioxins. Some commercial PCBs contained Incidental PCDF's at very low levela (up to 20 ppm). Monsanto Arodor* PCBs are recognised A* being the purest in the world. The PCDF content of Aroclors, according to the recent Hatlonal Academy of Science publication "Polychlorinated Biphenyls" (1979), ranged from 0-2 ppm, a level that is insignificant in comparison to levels found from combustion generation of these compounds in fires. The issue of PCBs, dielectric fluids (and other formulations) and fires is very complex. We have taken a sound scientific position based upon our products and intended uses. We can't respond for all other products which possibly contain many other chemicals that have significantly different propertles and could and do lead to other problems and Issues depending upon NEV 035227 in . to * *tv * t t * 803330 STLCOPCB4025863 S.

Although we don't seek to respond to all such prob lems, we will and do respond routinely to legitimate requests for infor mation about PCBs and possible effects in all sorts of uses and situations, Including health and safety emergencies,based upon analysis of the known facts. There Is no way to simplify our current KSDS type information more to cover all issues. If you have other questions, I'd be happy to discuss this Issue in depth at your convenience. /dg Attachment Craddock NEV 035228 < 803331 STLCOPCB4025864
